GHK (Tripeptide-1), also known as Glycyl-L-Histidyl-L-Lysine, is a naturally occurring tripeptide composed of three amino acids: glycine, histidine, and lysine. It is naturally present in human plasma, saliva, and urine, and plays an important role in tissue repair and skin regeneration.
In cosmetic and dermatological applications, GHK (Tripeptide-1) is valued for its ability to stimulate collagen production, support skin repair, and improve skin firmness and elasticity. It also helps enhance the skin’s extracellular matrix, which strengthens the skin structure and reduces visible signs of aging such as fine lines and wrinkles.
